Michigan Landfills Leak Methane: Outdated Reporting and Technology Failures Expose Environmental Threat

Methane gas leaking from Michigan landfills poses a significant environmental threat, exacerbated by outdated reporting standards and underutilized technology. Methane, a greenhouse gas 80 times more potent than carbon dioxide, is leaking from landfills across the country, including several in Michigan.

A study by Industrious Labs revealed discrepancies between methane leak reports from landfill operators and findings by the EPA, highlighting a severe underreporting issue.

Michigan has around 60 landfills, which are required by the Clean Air Act to self-report methane leaks quarterly using handheld devices. However, the EPA occasionally conducts inspections, uncovering more methane leaks than reported.

Notable examples include Brent Run landfill in Montrose Township and Pine Tree Acres Landfill in Macomb County, where the EPA found significant methane leaks and system failures during unannounced inspections.

The federal rules for methane leak reporting are outdated, akin to an old operating system, as per Industrious Labs. The current regulations mandate only quarterly self-reporting, which fails to capture the full extent of the leaks. Technological advancements, such as those used by Carbon Mapper, which employs airborne and satellite observations to document methane plumes, are available but not widely implemented.

Landfills are the third-largest source of methane leaks in the U.S., and the issue is considered highly solvable by experts like Katherine Blauvelt from Industrious Labs. Implementing existing technologies to reduce emissions is feasible and necessary.

The EPA has acknowledged the problem, stating that landfill inspections, identifying excess emissions, and enforcing compliance are part of their National Enforcement and Compliance Initiative for mitigating climate change.

Food waste is identified as the primary cause of landfill methane emissions, comprising about 25 percent of Michigan’s landfill contents. Rapid decay of food waste releases methane, making it a significant contributor to the problem. Addressing food waste and improving methane leak detection and reporting standards are critical steps toward mitigating the environmental impact of landfill methane emissions.
